Yes, you're messing it up...   :-)

If you insist on using local variables, then python is happily
decrementing their reference count as your 'constructor' goes
out of scope and they get garbage collected...

The convention is to make images instance variables. If you are
paranoid about seeing the variables, mangle their names:

    self.__secret_image = ....
